Damp proof sheeting

A damp proof sheet is a plastic membrane used as an underlay for a concrete floor. This waterproof
sheet is laid between the insulation layer and the sand base, and offers the concrete protection
against damp. The concrete is then poured on top of the insulation. Common examples include:

Epoxy damp-proof membrane - an epoxy resin for suppressing residual
rising damp in concrete. Applied by brush or roller in one or two coats.

Eco friendly alternatives

Plastic and polythene packaging are often considered less green than their glass or
paper-based alternatives. Plastic and polythene packaging are actually one of the
greenest forms of packaging and helps cost-effectively expand shelf-lives and reduce
wastage of food and other perishables. Did you know for instance that:

Polythene is significantly lighter than glass and paper and so results in
significantly lower carbon emissions when transported

Plastic packaging has a very low carbon footprint compared to glass and paper
requiring only a tiny fraction of the energy they need to produce

Plastic packaging can be recycled, cheapily and easily and requires less energy to
do so than paper, card or glass

Tips

How to damp proof your basement or cellar

Floor - Make a layer of sand then cover it with a layer of polyethylene
damp proof membrane which is a plastic sheet obtainable from Polybags Ltd. The sheet must be lapped up the walls and can be
secured using self adhesive tape. Any joints in the plastic sheet must be made by
holding about 10cm of each piece of plastic together then folding them so that one of
the pieces goes back on itself and the other lies on top. Then cover the plastic sheet
with sand/cement screed.

Walls - Use flashing tape to secure the plastic sheet which has been
lapped up the wall. Apply a sand/cement render on top of the waterproof coating, about
50mm thick.
